Problems solved by technology

[0005] However, in the process of promoting industrialization, the large-area flexible perovskite solar cell module using the upper substrate structure will have the following problems: (1) Preparing high-conductivity perovskite solar cell modules on high-transmittance PET or PEN plastic substrates The transparent conductive layer technology is difficult and the yield is low. Therefore, the price of flexible transparent conductive substrates based on PET or PEN is very high (the cost per square meter exceeds 10,000 yuan), which will lead to the cost of large-area components in industrial production. (2) When preparing la

Abstract

The invention relates to a flexile and large-area perovskite solar cell module and a preparation method thereof. The perovskite solar cell module comprises a metal back reflection layer, an electron transmission layer, a perovskite absorption layer, a cavity transmission layer, a transparent conductive front electrode, transparent packaging glue and a flexible and transparent plastic cover plate, which are stacked on a flexible substrate in sequence; light enters from a direction of the flexible and transparent plastic cover plate; the metal back reflection layer, the electron transmission layer, the perovskite absorption layer, the cavity transmission layer and the transparent conductive front electrode are separated by pre-set separation grooves to form a plurality of sub-cells which are connected in series. The flexile and large-area perovskite solar cell module has no requirements on permeability and conductivity of the substrate and the common and cheap flexible substrate can be adopted, so that the cost is remarkably reduced; the preparation method is simple in process, the rate of finished products is high and large-scale production is easy to realize; on the basis of not influencing performances of a perovskite solar cell, adverse effects on the perovskite solar cell, caused by external factors including water vapor, chemical corrosion, external stress and the like, can be avoided, and the reliability of the cell is improved.

Description

technical field [0001] The invention belongs to the technical field of titanium ore solar cells, and in particular relates to a flexible large-area perovskite solar cell component and a preparation method thereof. Background technique [0002] With the increasingly severe problems of the global ecological environment and energy shortage, clean and renewable solar photovoltaic power generation has received widespread attention from all countries. Perovskite solar cells have attracted the interest of a large number of researchers since they were first reported in 2009. After just a few years of development, its device efficiency has increased from 3.8% to 22%. The reason why perovskite solar cells are highly concerned by the photovoltaic field all over the world is that, in addition to reaching the high efficiency level of the first generation of crystalline silicon cells in a short period of time, more importantly, it is its low-cost preparation method. The industry has bro...
